'IMPROVEMENT IN PADLOGKS.

TO ALL IIA/HOM IT MAY CONCERN:4

Be it known that I, C. II. MILLER, of Frederick, Montgomery county, Pennsylvania, have invented certain Improvements in Padlocks; and Ido hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists of a casing to which is hung an arm and a lever, and in which are certain devices,

fully described hereafter, the whole being so constructed and arranged that the outer end of the said arm may."

be readily and firmly secured within the casing or removed from the same, when the devices contained therein are operated by a properly constructed key. l'

In order to enable others skilled in the art tomake and nse my invention, I will now proceed to describe its construction and operation. Cn reference to the accompanying drawing, which forms a part of this speciiication- Figures 1 and 2 are exterior views of my improved padlock, showing the parts in different positions'.

Figure 3, an exterior viewshowing the rear side of the lock. A

Figures 4 and 5, sectional views, showing the parts in diierent positions; and

Figure 6, a detached sectional view on the li'ne 1 2, rig. 4.

Similar' letters refer to similar parts throughout the several views.

A is a. circular lock case, 7J being the back, c the side or rim, and the cap-plate, Through projections r2 [Z passes a pin, c1., to which is hung a curved arm, B. In the outer end of the latter is an opening, 11;, and on the arm, near the said opening, is a shoulder, y. To a pin, c, within the case, is hung a pla-te, C, from which project two arms, it", the said arms being curved to correspond to a circle, of whichthe pin c is the centre, and at the lower side of the plate arc three projections, n nl in?. To the plate C is secured a spring-plate, m, which projects over and corresponds in shape with the arm z, the end of the latter, however, projecting slightly beyond the end of the spring-plate. The pin e passes `through aeurved spring, m', which bears against the cap-plate and against the plate C, and thus `retains the latter in any position to which it maybe adjusted. Toa' pin, c1, Within the case, is hung a lever, D, having two arms, o and o', and on the latter is a lug, j), which is maintained in a recess, s, in the edge of thc plate C by a spring, t. In the cap-plate are two key-holes or openings', q and Q', and to a pin in the eentreof the plato is hung a lever, E, a curved arm, r, at the inner side of which, projects into the interior of the case through a curved slot, w, in the back I) of the same; and against the said arm bears a spring, c, which tends to maintain the lever in the position shown in iigs. I3 and 4. To a pin, c2, is secured a spring, Z, which extends across the interior' of 'the case above the opening g, and rests with itsinnei` end against a lug, t. 0n apin, u, at the centre of the plate ZV, and at the outside of the latter, turns a disk, H, te which is secured a plate, I, and in the latter, above'akejhole, z, in the plate IL-is an opening, c. To the plate I is jointed a plate, Jl.' which, when inthe position shown in iig. I, covers the opening` e.

When the parts are in the position shown in tige. l and 4, and it is desired to release the arm B, the position of the plate I is reversed and the plate J is turned back to the position shown in iig. 2, so as to expose the keyhole q. A key, X, is then 4introduced int-o the key-hole q and turned in thc direction of the arrow, figs. 4 and 5. As the key is turned, it iirst raises thelong arm o of the lever D, so that the projection p ou the short arm ofthe latter is removed from the recess s. It then strikes the projection n2, and, bearing against the latter, turns the plate C a part of a revolutionin the direction oi' its `drrmv, I. rIhe key then passes from contact with the projection 7252 and is turned another revolution, when it will be brought against the projection nl, and will 'turn the plate C still further in the direction of its arrow, l. Asthe key is turned a second time the operator pushes backthe plate E in the direction of its arrow, figs. 3 and 5, and thus removes the'arm r from the open ing :15, so that when the plate C is brought to such a position that neither of the arms z' z'/ projects into the opening .1;,th-e arm B may then be raised, as shown in iig. 4. When the arm is again to be' secured in its iirst position the platcE is moved back and the plate C is brought to the position shown in iig. 4. The arm B is then depressed and the key is turned one revolution in either direction, when one of the arms, 'L' or t, will be introduced into the opening tc. The armr is. then permitted to resume its iirst position in the said opening. lhe opening q and spring Z serve to mislead any person unacquainted with the construction of the lock, and

thus render the l'atter more diicult to piek. It will be apparent that other devices than the plates I and J may be used to conceal the key-hole.

Without confining myself` to the precise construction and arrangement of parts herein described, I claim as my invention, and desire to secure by Letters Patent-- 1. The case A and arm B, with its opening x, in combination with the lever D and plate C, its arms t' z, projections n 911712, and recess s, the whole being constructed and operating substantially esA and for the purpose described.

2. The combination of the above and the plate E, and its arm 'r, for the purpose specified.

3; The plates I and H, with their openings z z and cover plate J, in combination with the case A and its key-holes q q, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
